Other claims from this paper (7)
- Observation A cDNA encoding cucumber CPD photolyase was isolated from leaves.
- Observation The cucumber cDNA protein sequence was highly similar to Arabidopsis CPD photolyase.
- Intervention effect The cDNA restored photorepair in an E. coli mutant, supporting functional cucumber photolyase identity.
- Observation CsPHR transcripts peaked at 09 : 00 in cucumber first leaves.
- Observation CPD photorepair activity peaked at 12 : 00 in cucumber first leaves.
- Intervention effect Midday supplemental UV-B had little effect on first leaf growth.
- Mechanism Authors suggest diurnal CPD repair activity, possibly regulated by CsPHR transcripts, minimizes UV-B growth inhibition.
